What is "foo" ?

Question

In many examples (c++) i have seen a variable name commmonly used .

That's " foo", "bar".

Does foo symbolises any special meaning .

Answer 1

foo and bar are just variable names created by someone with a sense of humour. They are thought to originate from the military slang FUBAR (F'd Up Beyond All Recognition) :) https://en.wikipedia.org/wiki/Foobar

Monical I totally agree. I much prefer the Monty Python variables spam, eggs and ham 😄
